BOTTLE CAP.

Application and June 9,

My invention relates to a sheet metal cap designed and adapted to form a closure for bottles or other receptacles. More particularly, it relates to a bottle cap of the two piece type comprising a top piece or button formed from one piece of sheet metal, and a flange or body formed of a separate piece of sheet metal.

An object of my invention is to provide an improved form of connection between the button and body, by which a strong rigid cap is produced.

A further object is to provide a cap having various advantages from a manufacturing standpoint as compared with caps of this type heretofore in use. 7

Other objects of the invention will appear hereinafter.

In the accompanying drawings:

Figure 1 is a part sectional elevation of a cap constructed in accordance with my invention, and the receptacle to which it is aplied. p Figure 2 is a plan view of the blank from which the body of the cap is formed.

Figure 8 is a section at the line IIIIII on Figure 1.

Figure 1 is a. fragmentary sectional view on an enlarged scale, of one corner of the The cap comprises a top portion or button 5 stamped from a piece of flat sheet metal, and a body 6 formed from a separate blank of sheet metal of the shape shown in Figure 2.

The button 5 is formed with an inner annular bead 7 adjacent its periphery which protrudes downward or inward, and an upwardly projecting outer annular head 8 at the periphery of said button. The outer wall of the bead 8 is extended downward to form a vertical flange 9. The heads 7 and 8 preferably merge into each other, forming in cross section a compound curve.

The body 6 is formed from the blank, Fig. 2, by uniting its ends 10 and 11 to form an intertolded seam 12. The upper edge of the body 6 is curved inwardly and downwardly to form an annular gripping portion 10 which fits over the head 8, the lower edge of the part 10 projecting downward into the groove 7. When the parts are assembled,

the curved portion 10 is caused to grip the head 8 and thereby securely unite the parts. It will be noted that with this construction,

there are four thicknesses of metal at the upper peripheral portion of the cap, including the two side walls of the bead 8 and the two side walls of the part 10. Inthis manner, a strong and rigid construction is produced, permltting the use of comparatively thin sheet metal and thus eflecting a substantial economy of material. The downwardly extending flange 9 of the cap adds strength and rigidity to the cap. Said fiange extends downward a sufiicient distance to cover the notch 13 which is ordinarily formed in the body of the cap at the upper end of the seam 12.

The cap, as herein shown, is applied to a bottle 14, the upper edge or lip 15 of which is substantially the same diameter as the bead 7, so that said lip comes directly beneath and in register with the head. A liner 16 of cork or other suitable material provides a perfect seal between the bottle and the cap. When the cap is ori 'nally applied to the bottle, the lower edge 1 of the cap is flanged or bent inwardly beneath an annular bead 18 formed on the neck of the bottle to thereby hold the cap against displacement. The cap is formed with a weakened line or score 19 which extends circumferentially of the cap and provides a removable strip 20, the end of which is extended to form a finger piece 21.

When it is desired to open the bottle, the strip 20 is torn off, allowing the ca to be removed. After the cap has origina ly been removed, it serves as a temporary closure for the bottle and can be taken oil as often as required in dispensing the contents of the contamer.

By placing the bead 7 directly over the lip of the container, the pressure with which the cap is originally applied, is applied directly over the bottle lip in a manner to form an efiective seal. The beads 7 and 8 also impress the liner and assist in holding it against accidental displacement when the cap tion to conceal the raw edges, as has hitherto been considered necessary with this type of cap, is, therefore, entirely unnecessary with the present invention, thereby permitting the use of the construction herein shown with its attendant advantages. I

Modifications may be resorted to within the spirit and scope of my invention.

What I claim is:

l. A cap for a container, comprising a button or top portion and a body portion formed of separate pieces of sheet metal; said button being formed with an inner annular downwardly projected bead adjacent the periphery of the button, and an outer annular bead surrounding and extending upward from said first mentioned head, the outer wall of said outer bead being extended vertically downward to form a peripheral flange on the button extending into the body portion; said body portion being formed of a strip having its ends united in an interftolded seam terminatinr a short distance below the upper edge of said body, the upper edge portion of the body being curved 1nwardly and downwardly to embrace the outer head of the button and trictionally hold said top and body portions together, permittin them to be assembled or separated solely by a relative endwise move ment.

.2. The combination of a container and a cap therefor, said cap comprising a circular top portion, body portion, and a liner, said top and body formed of separate pieces of sheet material; the top being formed with an inner annular bead projecting downwardly and directly overlying the upper edge or lip of the container, and an outer peripheral bead surrounding and projecting upwardly above said inner bead and terneaaaaa minating in a depending circumferential flange surrounding the upper end of the container and of substantially greater diameter than said end. said liner being seated in the can and held under compression between the li of the bottle and said inner head, said body having its upper edge curved inwardly to embrace said outer bead and trictionally hold said top and body portions together, permitting them to be assembled or separated solely by a relative endwise movement, the neck of said container being formed with an annular rib spaced below the lipiot the container, said body of the cap having its lower edge bent inwardl to underlie said rib and therebv secure the cap on the container, the cap being formed with a circumferential score adjacent its lower edge providing a removable strip.

3. A cap for a container, comprising a circular top portion and a cylindrical body portion formed of separate pieces of sheet metal, said top portion formed with an upwardly protruding bead extending circumt'erentially thereof and forming the periphery of said top portion, the outer wall of said head being extended downwardly to form a peripheral flange telescoping into the upper end of the body portion, said body ortion having its upper edge portion curved inwardly and downwardly to embrace said head and frictionally holding the bead, whereby said top and body portions may be united solely by an endwise movement of the top portion into the body portion and held together bv frictional contact.
